I've updated the statistics. Obviously, December is the time when most sales are made, so it should be reflected here. I also included MIDI keyboards this time. Certainly, there're a lot of sales made outside this resource and they are not shown here. But so far, within this picture, these are the products which people buy in Russia. Those models which are missing here do not have any number of sales, presumably, it means that no sales were made.
I had to make this sheet manually, so some errors are possible.
No certain message here, just numbers to share.
